| titleOfInvention | Modified lithium manganate positive pole material and preparation method thereof |
| abstract | The invention provides a modified lithium manganate positive pole material which comprises a main body material and oxide particles which are discontinuously distributed on the surface of the main body material, wherein the main body material is composed of a compound disclosed as Formula (I) in specific atomic ratio; the chemical formula of the oxide is disclosed as Formula (II); and the mol ratio of the oxide particles to the main body material is y, and 0<y<=0.5. The invention also provides a preparation method of the modified lithium manganate positive pole material. In the modified lithium manganate positive pole material provided by the invention, the oxide particles on the surface first react with trace amounts of HF in the electrolyte to reduce the dissolution of the element manganese in the main body material, so that the lithium ion battery has favorable high temperature property and filling property. The oxide particles are discontinuously distributed on the surface of the main body material, but not coated on the surface of the main body material, thereby avoiding impedance increase due to the existence of the coating layer. |
